A North Carolina politician is taking some heat over the language his resignation letter was written in.

David Waddell tenured his resignation from the Indian Trail Town Council on Thursday, but did so by submitting a letter written in Klingon, the language of a warrior race on the "Star Trek" TV shows and movies, The Associated Press reported.

Waddell said it was meant as an inside joke.

But Indian Trail's mayor isn't laughing, and has called the letter unprofessional.

Waddell is leaving at the end of this month to mount a write-in campaign on the Constitution Party's platform against U.S. Sen. Kay Hagan.
